Using Disk Copy 4.2

[habibrobert]

Hello,

I am trying to make an installer disk for a color classic. I am going to install OS 7.1. I know that I need an installer for this task and I have been able to find the system enabler as well as the installer. My question is: is that all I need to make an installer disk? And if so, can I use disk copy 4.2 to make a new disk image, or does it only work for copying the contents of one floppy to another?

Thanks.

You use Disk Copy to write a disk image to disk. As far as the Enabler, you just have to drop that in the System folder.

DC 4.2 cannot create disk images, only image floppies or write out a few formats it supports.

To create a disk image from a floppy, you need to use Disk Copy 6.3 (I've got it and I can email it to you if you want it). However, Disk Copy 4.2 is fine for copying one floppy to another (although you can do that from the Finder) or for writing special format image files to floppies (although Disk Copy 6.3 will handle Disk Copy 4.2-format image files and normal ones, so there's really no reason not to use it).

Of course you can create images with Disk Copy 4.2. Just pop in a disk and click "Read Master Floppy". Once the disk has been read in, go to File > Save Image. You have now just saved an image of your disk.

PS I though Disk Copy 6.3 didn't make a "true" byte-for-byte copy and could give unexpected results when used on non-System 6.0.8 systems. Or an I thinking of something else?

Thank you, Krye. I was going to say the same thing.

I was not aware of the limitations of Disk Copy 6.3.3. I'm glad you guys mentioned it.

It cannot create images like DC 6.1+ or ShrinkWrap can, being that it would create a new virtual disk, then you can copy junk on to it, then "close it up" to generate the new image.

You're probably thinking of the issue DC 6.3.3 has (not sure about 6.1.3, but it's probably the same deal) when imaging 800K/400K disks. That and it doesn't work under System 6.

I was able to use both disk copy 4.2 and 6.3. I am using a mac G3 along with an external floppy drive, so disk copy 6.3 would not allow me to write an image to an external drive.

I forgot to mention something which may be important. I am trying to create an installer disk for installing OS 7.1 on a mystic color classic.

Basically what I have done so far is copy the installer and system files from the OS 7.1 installer floppy (for a normal color classic) minus the enable (which I believe is enabler 401) and put them in a folder on my desktop. Then I added enabler 065 into that same folder. To put it in another way, I am using all the files you would use for a installer disk for a regular color classic except for a different enabler.

Then, I created an image of that using disk copy 6.3 and then loaded it into disk copy 4.2 and copied it onto a floppy disk. I tried it on my mac but it just ejected the disk.

Could someone tell me what could be wrong? This is my firs time making an installer disk.

Thanks

DC 4.2 cannot read NDIF images. ShrinkWrap can though.

I'm under the assumption you have access to some sort of 7.1 install or installer. Why not use the 7.5NAD from Apple with an AFP bridge to the iMac and push the whole shebang over the network?

While you're at it, I'm not sure exactly how the CC will work, but creating a 7.1NAD of your own is probably possible, although I'm not sure how much better it will be than the 7.5NAD. (They really should have made a 7.5.3NAD 68K and 7.5.3NAD PPC...)

 

[habibrobert]

I tried using 7.5 NAD on the CC everything seemed to work fine until I got a bus error. I tried restarting while pressing down the shift key to turn off the extensions, but still no luck. I am assuming this is because of the LC 575 board thats in the CC.

I just realized that the system enabler I am using is 065 version 1.2 and not 1.1. I have heard on the web that only enabler 065 system 1.1 will work for the mystic upgrade. If this is true, where could I find that enabler? The apple website does not have this particular version.

Anyone out there have a disk image for the installer for 7.1 mystic upgrade or have the correct enabler?

 

[Mk.558]

If anybody did have the disk image, we wouldn't be able to post it here because it'd be in contradiction of the forum rules.

Try looking at Gamba's site.

I was able to find Enabler 065 version 1.1 on mac512.com, but that did not work. There must be something that I am doing wrong. I noticed that everyone is saying that you have to put the enabler in the system file, but I tried to drag and drop it into the system file that was present in the original Installer disk for the CC, but the computer did not allow me to insert it into the system folder. Am I misunderstanding or missing something?

Thanks again for your help. By the way, I really enjoyed reading your article on how to use disk copy 4.2 and the likes. It was really clear and simple to understand for someone of my low technical level!

Enablers don't go in the System file itself, just the plain System Folder.

This is what I suggest: Install 7.5.3 first. If you don't have an LC-PDS Ethernet card, you should get one. They are not that expensive and are way, way better than LocalTalk (20KB/sec max, -ish), RS232 terminal (at 115200bps, it's about 11KB/sec), AFP bridges (only work over AFP over AppleTalk).

Then when the CC can support itself, then you can try another method: Install 7.1 from however you'd like to do it, I'd do it via disk images copied over the network because floppies are dead slow (8-9KB/sec write, typical), then try get ahold of every single enabler you can find, and use System Picker to select the boot volume. Although partitioning the drive so that each OS gets its own partition, System Picker makes that concept pointless and in fact works perfectly fine. Then make take a 7.5.3 or 8.1 Disk Tools disk and delete the other stuff on it, and put System Picker on it: make sure the disk works beforehand, and if it does, make a NDIF backup of it just in case the floppy gets weaklegged, as it's the "saving grace" for a System that doesn't have a blessed System Folder. Finally, start removing the enablers one by one until "The One" is isolated. :cc:

I am not sure what motherboard to use for this whole process, so let me try and re-cap what you said with what I understood....

I have not done the screen upgrade for my CC to have OS 7.5 supported with the Mystic upgrade. So I am assuming that I need to take out the LC 575 motherboard and put in the original CC mother board and install 7.5?

Then install 7.1 with the CC motherboard still inside and install system picker. With system picker I then choose the system folder I want to "bless" upon start up.This is the part where I am able to test all the different enablers, correct? Then I need to take a Disk Tools disk and put system picker on it as well? Here I don't understand why I need to do that?

Sorry if I totally misunderstood what you said! By the way, I'll look into that getting an Ethernet card, I'm going to need one if I ever want to surf the net with this guy (assuming I can ever get it up and running).

I wouldn't know for sure, as I've never done a Mystic, but I'd leave the LC575 mobo in there, and take care of the VGA upgrade in hardware. Seems pretty easy. I'll wager they are SMD resistors, which still aren't too bad.

If there are compatibility problems, then there is always 8.1. I'd do just a Minimal install with just the stuff you'd need to make it do what you need for the time being. System Picker 1.1a3 is the one to have -- 1.0b10 won't get out of 8.1.

The Disk Tools disk (assuming it will boot the machine) is in case you get stuck with a :?: .

 

[habibrobert]

thanks very much for all the help. I'll give all this a shot once I am able to preform the hack on the motherboard in order to use OS 7.5. I will let you know how my results.
